Note that the same magnet file works like a charm in the Desktop APP

Those messages are because only websocket trackers work in the browser (not udp or http). You need at least one to connect to other peers in the browser.

Webtorrent-desktop can handle those types of trackers just fine though, so that's why it works there.

I think it's OK for you to use these public trackers.

• wss://tracker.btorrent.xyz
• wss://tracker.openwebtorrent.com
• wss://tracker.fastcast.nz

Just add them to the magnet link like this

&tr=wss://tracker.btorrent.xyz&tr=wss://tracker.openwebtorrent.com etc

You don't have to remove the others, they just won't work in the browser, and they'll still give you the annoying errors. They won't break anything though.

 

I still don't think it will work though, because there has to be at least one client seeding the torrent for you to be able to download it, and that client has to be compatible with webtorrent (webtorrent-desktop, webtorrent in browser, or vuze)

They also have to be using one of the same trackers as you I think, so if you're just trying to download a normal torrent in the browser, it likely won't work. (you can try after adding the websocket trackers though)
